This application is a continuation of U.S. patent application Ser. No.16/074,067, filed Jul. 30, 2018 which is incorporated by referenceherein in its entirety.

TECHNICAL FIELD

The present invention is related to the field of Communications, andspecifically to a method and apparatus for connection processing betweena terminal and base station.

BACKGROUND TECHNIQUES

Machine to Machine (M2M) Communication is currently an important areafor research in fifth generation mobile communication technologies (5G),and is an important field for application for the future of wirelesscommunications. Within the scope of M2M research are NarrowBand-Internetof Things (NB-IoT) subtopics aimed toward terminal features such as lowcost, low power consumption, low mobility, and low throughput; that is,to provide within the 200 khz frequency range a low-throughput wirelesscommunication service for NB-IoT low-cost terminals.

In order to reduce signaling overhead and NB-IoT terminal powerconsumption, the existing research has led to two modes of small datatransmission:

1. The control plane optimization mode (CP mode); Data Radio Bearers(DRB) will not be established between the terminal and network, neitherwill the Access Stratum (AS) security context be established. Data ispackaged into Non-Access Stratum Protocol Data Units (NAS PDU) andattached to the control plane signal for transmission; this mode yieldsrelatively obvious conservation of signaling, but the length of datapackets transmitted at one time is limited. Relatively larger datapackets must be separated into multiple smaller packets fortransmission. When coverage is relatively poor, it is easy to losepackets, which makes it difficult for the receiving party to receive acomplete data packet.

2. The user plane optimization mode (UP mode): the terminal and thenetwork establish a complete connection, using DRB to transmit data;after data transmission is complete, the bearer information context, theAS security context, etc., is saved in the terminal and network-sidethrough the suspend-activate procedure. When data is transmitted oncemore, both parties resume the previously stored context throughrestoring the procedure, and continue to use DRB bearers to transmitdata. This mode does not differ greatly from the existing process, anddoes not limit the length of data packets in any obvious way, but itsability to conserve signaling has limitations.

The existing research has also introduced a process of capacitynegotiation between the terminal and network. When the terminalinitially attaches, the Attach Request carries an optional PreferredNetwork Behavior Indication message, indicating the terminal'ssupportable Network Behavior: 1, whether the control plane optimizationmode is supported; 2, whether the user plane optimization mode issupported; 3, recommendation for using the control plane optimizationmode or the user plane optimization mode; 4, whether the S1-u datatransmission function is supported; 5, whether to require that the shortmessage not be implemented with the attachment.

The MME network element of the network-side will include the SupportedNetwork Behavior in the Attach Accept message to indicate the NetworkBehavior it is able to accept.

After the terminal and network-side negotiate to adopt the UP mode, whenthe terminal has uplink data requiring transmission, the air interfaceand network-side bearer resumption process must be triggered. When thenetwork-side has downlink data requiring transmission, it will firstpage the terminal and then trigger the terminal to initiate the airinterface and network-side bearer resumption process.

In the process of researching the standard RRC connection resumptionprocess of existing technologies, the following approaches have beendiscussed with regard to the air interface resumption process: 1.defining a new RRC connection resumption request/resumption responsemessage; 2. continuing to use the existing RRC connection establishmentprocess, and adding new instructions; 3. continuing to use the existingRRC connection reestablishment process, and adding new instructions.

Beyond this, some researchers suggest that if the terminal has data itwants to transmit, it is also possible to package the data as NAS PDU orDRB multiplexing, etc., that is carried in some uplink air interfacemessage of the resumption process; for example, carrying it in the airinterface resumption request, the air interface connection establishmentrequest, or the air interface connection establishment completionmessage.

Through the course of our research, we have found that within theforegoing approaches exist the following problems:

1. Presently, after suspension and before resumption, the terminalexists in an Idle state. After resumption the terminal exists in aConnected state, the same state as the terminal before and after the RRCconnection establishment process, but the resumption process can be afailure for any number of reasons, such as rejection caused bycongestion, wireless link failure caused by anomalies, etc; most of thefailures that terminals initiating RRC connection establishmentprocesses can encounter are similar. In addition, the expectedprocessing mode after resumption failure, such as notifying thehigher-layer to implement anomaly processing, or waiting a period oftime before re-triggering access, etc., are similar to the processingmodes used by the terminal after failure to initiate the RRC connectionestablishment process: if a new RRC connection resumption requestmessage and its corresponding procedure were to be introduced, a largenumber of processing repetitions would occur.

2. In the resumption process it is possible to transmit NAS PDU ofpackaged user data; currently, in NAS (non-access stratum) and AS(access stratum) interaction, NAS signaling is only able to trigger theRRC establishment process; if a new resumption request message and itscorresponding procedure were to be introduced, the NAS protocol could bemore greatly affected. Requiring consideration is how NAS signalingcould trigger a new RRC connection resumption request message and itscorresponding procedure.

3. Before the terminal triggers the resumption process, variouscontextual information required by the user plane optimization mode hasalready been stored on preset terminals, base stations, and relatedcore-network network elements. When a terminal appears because of someanomalous factor, the context information stored in any node on thecore-network network element and base station is deficient; this is anew anomaly requiring a fast-paced processing mechanism.

4. Before the terminal triggers the resumption process, various contextinformation required by the user plane optimization mode has alreadybeen stored on preset terminals, base stations, and related core-networknetwork elements. How to identify this context information so that theterminal and the base station are able to adopt consistent identitysearches and resume the correct context information is as of yetinconclusive. Presently, some terminal identities defined in thestandard are primarily allocated in the terminal connectionestablishment process or used after terminal connection establishmentcompletion, and are not necessarily suitable for identifying the contextbelonging to the terminal after the connection release. It is thus thatan optimized resumption identity definition must be considered.

As for the complicated nature of the connection processing between theterminal and network in the related technology, there has presently yetto emerge an effective resolution.

Embodiment 1

The present embodiment provides a method for connection processingbetween the terminal and network. FIG. 1 is a flowchart of an optionalconnection processing method between the terminal and base station basedon the embodiments of the present invention. As FIG. 1 shows, theprocedure comprises the following steps:

Step S102, the base station receives the first request message carryingthe terminal identity information that is transmitted by the terminal,wherein, the terminal identity information is used to indicate theidentity of the terminal, and the first request message is used torequest the base station to resume the connection between the terminaland network;

Step S104, the base station searches for context information matchingthe terminal identity information;

Step S106, when the base station finds the context information, it usesthe context information to resume the connection with the terminal.

Alternatively, the above steps can be applied to resuming a wirelessconnection or to a user plane optimization scenario, especially to anRRC connection resumption scenario, such as: with NB-IoT technology,when the user plane optimization mode is adopted, the scenario wherebyRRC connection between the base station and the terminal is resumed.

Since the terminal requesting connection resumption could have alreadyestablished a connection with the base station before, and the basestation may have retained the terminal's context information, therequest message received by the base station carries a connectionrequest message, which can instruct the base station to preferentiallyresume the connection with the terminal; the base station searches forwhether the context information matching the indicated terminal identityinformation is present based on the terminal identity informationcarried in the request message; if the context information is found, thebase station directly resumes connection with the terminal based oncontext information; the implementation of the above steps therebysolves the problem of complex connection processing between the terminaland base station in the related art, and achieves high-speed connectionresumption between the terminal and network. Beyond this, the basestation makes use of the original context information, thereby avoidingthe repeat execution of a connection establishment flow and improvingthe efficiently of connection processing between the terminal andnetwork.

Within the present embodiment, terminal identity information can, but isnot limited to, comprise at least one of the following: initial terminalidentity information, resumption identity information; wherein, initialterminal identity information comprises: initial terminal identity orinformation used to generate initial terminal identity; resumptionidentity information comprises: resumption identity or information usedto generate resumption identity.

The following describes the terminal identity information through theuse of examples.

Terminal identity information can directly carry initial establishmentidentity and resumption identity; it can also carry information able togenerate the initial establishment identity and resumption identitybased on the need to resume connection. For example, suppose the initialestablishment identity is composed of the initial establishment identityvalue of the first bit value and a pseudo-random code of the second bitvalue, and the resumption identity is composed of the resumptionidentity value of the third bit value and a pseudo-random code of thefourth bit value; one type of terminal identity information can carrythe combined initial establishment identity and the combined resumptionidentity; another type of terminal identity information can directlycarry the initial establishment identity value of the first bit value,the pseudo-random code of the second bit value, the resumption identityvalue of the third bit value, and the pseudo-random code of the fourthbit value; based on the indication, the initial establishment value ofthe first bit value and the pseudo-random code of the second bit valueconstitute the initial establishment identity, or, based on theindication the indication, the resumption identity value of the thirdbit value and the pseudo-random code of the fourth bit value constitutethe resumption identity.

Alternatively, after Step S104, when the base station has not found thecontext information, it can obtain the context information from theneighboring base station and resume connection with the terminal usingthe context information obtained in the neighboring base station. Whenthe base station has not found the context information, the base stationcan further use the terminal identity information to establish aconnection with the terminal.

Alternatively, the first request message can, but is not limited to,comprise one of the following: the resumption request message, a messagecarrying the connection resumption indication.

Alternatively, the message carrying a connection resumption indicationcan, but is not limited to, comprise at least one of the following: theRRC connection request message, the RRC connection reestablishmentrequest message.

Alternatively, in Step S104, when triggered by the first requestmessage, the base station can preferentially search for contextinformation that matches the resumption identity information; afterwhich, if the base station has not found the context information, it canestablish an RRC connection with the terminal based on the initialterminal identity information.

Alternatively, after Step S104, when the base station has not found thecontext information, it can further transmit a reject message to theterminal, wherein, the reject message carries a reject cause value orindication information, wherein, the indication information is used forthe terminal to determine whether to reestablish the connection with thenetwork.

Within the present embodiment, the reject message can, but is notlimited to, comprise at least one of the following: the RRC connectionreject message, the RRC reestablishment reject message, the RRCconnection resumption reject message.

Within the present embodiment, the initial terminal identity can, but isnot limited to, comprise: identity information with length not exceeding41 bits; information used to generate the initial terminal identity can,but is not limited to, comprise at least one of the following:SAE-Temporary Mobile Subscriber Identity (S-TMSI), Mobile ManagementEntity (MME) identity MMEC, MME user unique identity code m-TMSI, cellidentity, unique terminal identity number C-RNTI, ShortMac-Iinformation, a random number with length not exceeding 32 bits;resumption identity can, but is not limited to, comprise: identityinformation with length not exceeding 41 bits; information used forresumption identity can, but is not limited to, comprise at least one ofthe following: SAE-Temporary Mobile Subscriber Identity (S-TMSI), MobileManagement Entity (MME) identity MMEC, MME user unique identity codem-TMSI, cell identity, unique terminal identity number C-RNTI,ShortMac-I information, a random number with length not exceeding 32bits.

The present embodiment further provides a method for connectionprocessing between the terminal and network, wherein, the methodcomprises the following steps: the terminal transmitting the firstrequest message carrying the terminal identity information to the basestation, wherein, the terminal identity information is used to indicatethe identity of the terminal, and the first request message is used torequest the base station to resume the connection between the terminaland network.

Alternatively, the message of the existing RRC connection establishmentflow can be used to execute the air interface resumption flow betweenthe terminal and network.

Alternatively, the first request message can be an RRC ConnectionRequest, which can simultaneously carry the initial establishmentidentity and the resumption identity acting as the terminal identity.The base station can, but is not limited to, preferentially use theresumption identity based on the resumption indication.

Alternatively, the resumption identity can be a combination of C-RNTIand Cell Identity (ID) information.

Alternatively, a new connection resumption indication can be added tothe RRC Connection Request; for example, a connection resumptionindication indicating the preferential use of the resumption identityinformation.

Alternatively, after Step S1604, the base station can receive the thirdresponse message used to indicate the network-side establishing orresuming a connection result with the terminal, and when it receives thethird response message indicating the network-side has established orresumed connection with the terminal successfully, connection betweenthe base station and the terminal is established or resumed.

Alternatively, after the base station receives the third responsemessage used to indicate the network-side establishing or resuming aconnection result with the terminal, the base station could receive athird response message indicating the network-side establishing orresuming connection with the terminal unsuccessfully, but the basestation receives the context information that matches the resumptionidentity information successfully; under these circumstances, the basestation can reestablish the connection between the terminal and network.

Alternatively, after notifying the network-side to establish or resumeconnection with the terminal, the base station can receive a thirdresponse message indicating the network-side establishing or resumingconnection with the terminal unsuccessfully; in addition, the basestation does not receive the context information that matches theresumption identity information successfully; under these circumstances,the base station transmits the reject message to the terminal, wherein,the reject message is used to reject the requested operations of therequest message; the reject message carries the rejection cause value.

Alternatively, after the base station transmits the reject message tothe terminal, the terminal can disregard the transmission process of therandom access preamble and once more transmit the request messagecarrying the terminal identity information to the base station.

The present embodiment further provides a method for connectionprocessing between the terminal and network, wherein, the methodcomprises the following steps: the terminal transmitting the thirdrequest message, carrying the terminal identity information, to the basestation, wherein, the terminal identity information is used to indicatethe identity of the terminal, and the third request message is used torequest the base station to establish or resume connection between theterminal and network.

Alternatively, after transmitting the third request message carrying theterminal identity information, the terminal can extend the time value ofthe timer; or, it can extend the time value of the timer based on thebase station indication, wherein, the time value is the time theterminal waits for the base station to transmit the response message.

The following describes the connection processing procedure of thepresent embodiment based on an optional mode of implementation. FIG. 17is another flowchart of a method for connection processing between theterminal and network based on an alternate embodiment of the presentinvention. As is shown in FIG. 17, the procedure comprises the followingsteps:

Step S1716, the base station receives the completion message transmittedby the terminal.

FIG. 18 is another flowchart of a method for connection processingbetween the terminal and network based on an alternate embodiment of thepresent invention. As is shown in FIG. 18, the procedure comprises thefollowing steps:

Step S1802, message 1 is the random access preamble transmission betweenthe terminal and the base station.

Step S1804, the base station transmits message 2 to the terminal: therandom access response.

Step S1806, the base station receives the request message carrying theterminal identity information transmitted by the terminal, wherein, therequest message carries the resumption identity (e.g., Resume ID).

Step S1808, the terminal extends the time value of the timer.

Step S1810, the base station requests from the network-side a requestmessage resuming S1 interface resources.

Step S1812, the base station receives the response message of resumingS1 interface resources of the network-side.

Step S1814, the base station transmits the third request messagecarrying terminal identity information to the terminal.

Step S1816, the base station receives the completion message transmittedby the terminal.

The base station to successfully resuming or establishing an RRCconnection could require that the RRC connection of the air interfaceand the RRC connection of the network-side are both resumed orestablished successfully; after the RRC connection with the terminal isresumed or established through the air interface, the network-side mustbe notified to resume or establish an RRC connection. In somecircumstances, the RRC connection could have no way of resumption orestablishment because the network-side's resumption is unsuccessful. Forexample, when the base station cannot find context information matchingthe terminal identity, the base station can transmit the RRC ConnectionReject message to the terminal. A rejection cause can be added to theRRC connection reject message, such as context resumption failure.

In order to make the descriptions of the embodiments of the presentinvention even more clear, the following combines alternativeembodiments for the purpose of explanation.

Within an alternative embodiment, the first response message uses theRRC connection resumption success response as an example.

The present alternative embodiment provides a method for coordinating anRRC connection resumption with an air interface and a network-sideprocedure in a user plane optimization scenario.

Within the present alternative embodiment, when the base stationreceives the request message related to the RRC connection resumptionprocedure transmitted by the terminal (it could be an RRC ConnectionRequest, an RRC Connection Reestablishment Request, a newly added RRCConnection Resumption Request message, or a different message), and whenit carries a resumption indication, the base station first triggers thenetwork-side to bear an RRC connection resumption procedure; afterreceiving the RRC connection resumption success response, the responsemessage related to the RRC connection resumption procedure (it could bean RRC Connection Setup, RRC Connection Reestablishment, a newly addedRRC Connection Resumption Response message, or a different message) isthen transmitted to the terminal. The base station can directly link theair interface bearer with the core-network bearer in the responsemessage.

Within the present alternative embodiment, when the base stationreceives the request message related to the RRC connection resumptionprocedure transmitted by the terminal, and when it carries a resumptionindication, if the base station has no way of finding the contextinformation that matches the terminal identity, it can simultaneouslytrigger the network-side to bear the RR C connection resumptionprocedure and the X2 interface to bear the RRC connection obtainmentprocedure. If the base station receives successful responses from both,it can transmit the response message related to the RRC connectionresumption procedure (e.g., the RRC Connection Setup, the RRC ConnectionReestablishment, a newly added RRC connection resumption responsemessage, or a different message) to the terminal The base station candirectly link the air interface bearer with the core-network bearer inthe response message.

Within the present alternative embodiment, if only the network-sidebearing the RRC connection resumption procedure is initiated, and itsucceeds, or the network-side succeeds in bearing the RRC connectionresumption procedure but the X2 interface does not succeed in bearingthe RRC connection obtainment procedure, the base station can use theS-TMSI to complete the subsequent connection establishment procedure;within the response message related to the RRC connection resumptionprocedure transmitted from the base station to the terminal, the airinterface bearer and core-network bearer can be directly linked.

Within the present alternative embodiment, if the network-side bears theRRC connection resumption procedure unsuccessfully but the X2 interfacebears the RRC connection obtainment procedure successfully, or if bothare failures, the base station can transmit the RRC connectionresumption reject message (e.g., RRC Connection Reject, to the terminal,RRC Connection Reestablishment Reject, newly added RRC connectionresumption reject message, or a different message) to the terminal. Anew rejection cause can be added to the RRC connection reject message,such as: network-side or base station-side context resumption failure,etc.

The adoption of the methods of the present embodiments can both perfectthe signaling procedure of the user plane optimization mode and rapidlyprocess anomaly circumstances.

Through the descriptions of the above embodiments, it will be apparentto those skilled in the related art that the above methods can beimplemented using software and the necessary universal hardwareplatform, and can also be implemented with hardware, but for manycircumstances the former implementation mode is ideal. Based on thisunderstanding, the technical solutions of the present inventionthemselves, or the portion of which that will contribute to the existingart, can be embodied in the form of computer software products stored ona storage medium (e.g., ROM/RAM, magnetic disks, optical disks),comprising several instructions used to make a terminal device (e.g., aphone, computer, server, or network device, etc.) implement each methodof the present embodiment.
